ok this is more of a answer
the next dbz game coming out is called "Dragonball:Raging Blast" (note there is no Z but it is still based on DBZ) it will be out for PS3 and Xbox 360
the next dragonball game for Wii is "Dragonball:Revenge of King Piccolo"
(being based on DB with kid goku) and it is also based on the drawing of Akira Torioma the maker of Dragonball/Z
the drawings in the dragonball:revenge if king piccolo are very much like Akira Torioma's drawings
sorry i mean "-revenge of-" not if
